In Australia there is talk of providing broadband internet by building a Fibre To The Home (FTTH) network using overhead cables. That is what is done in Cambodia and Vietnam. It is not pretty. This photograph was taken in Phnom Penh.
I was advised that an individual calls up one of the many phone companies, asks for a connection, and the workers for that phone company open a new connection in the exchange, and run it to the premises, attaching it to whatever poles are handy. That tangle of black cables is the fibre cable.
